My son will be 4 next month. He's never slept close to what he 'should'. He's been running on 9hrs daily total since age 2. Some days he only does 8 hours nowadays. It's exhausting! He gets up around 4-4:30 in the winter and 5-5:30 in the summer. No naps. Can't fall asleep at night. Definitely can not go back to sleep in the morning. Xmas morning he got up at 3:30 - and we know when he's up he's up, so we did presents then. DS get's sick rather easily and I wonder if it's related to not getting adequate sleep.
